Wait...you need saddle bags for a GoldWing???
After using your link I was reminded of the Valkyrie!
IMHO, with Viking you get what you pay for or, GOOD "Price to Value ratio". I had a set of "Pleather" bags on a Honda VTX 1300 R that held up well even with constants use. You may need to do a little modification here and there to make them fit. After drilling the mounting holes in the bags I added some metal plates for more support where the inside wall of the bags sit next to the mounting rail.
